I've been using the camera for a few weeks now and I'm quite satisfied. The solar panel supplies the battery with enough power. In my case, the solar panel is not exposed directly to the sun or only for a short time and the battery is still 100%.

The image quality is sufficient and the night vision is good for 2-3m. The motion detection works, but could trigger a little faster.

Unfortunately, the management of the recordings only works via the CloudEge app. Therefore, the camera cannot be integrated into any other systems. Anyone who can live with that and has no power supply available at the camera location is well served with the camera.

In search of a surveillance camera, I came across this LTE camera from K&F Concept.

For me, 2 points were crucial:
1. the camera should be able to operate without external power source.
2. the camera should have online functions.

To point 1:
The K&F Concept 4g camera has a built-in battery. The battery can be charged via an enclosed cable. In addition, there is a solar panel in the scope of delivery, which can be mounted directly on the camera or on the house wall. In the past weeks, it was relatively sunny and the battery was always fully charged by the solar panel. I am curious whether this will also be the case in the fall / winter.
To point 2:
The camera has WLAN and a SIM card slot. A trial SIM card is included in the scope of delivery. K&F Concept offers cloud storage of the video material for a corresponding fee. The camera can also be connected to the WLAN and controlled and configured via the K&F Concept app.

The built-in motion detection activates the camera and sends a push message to the app. The camera can be rotated in the app, in two directions, 355°/ 95°.
Both during the day and at night, the camera offers good picture (2K).
The two-way sound is acceptable, but depends on where / how high the camera is mounted.

So far I am very satisfied with the product.

An absolute gem with the latest and innovative technology. It is the best security camera I have that is completely wireless, self contained and has a solar panel to charge the battery so I don't have to take it off every 2 months to recharge.

What a nice design as the plastic used for this unit is a high quality material and comes with all the hardware, including a paper template for drilling holes to ensure a perfect installation. It also comes with an extra USB cable just in case you need to charge it with a USB charger, but my camera was 100% charged when it arrived, which shows that when it's off, there's no battery drain and it doesn't self-discharge.

What I love most is that it has a fully motorized head, so you can pan the head in all directions with your phone to check what's going on outside. I am very impressed with this feature because all 4 of the security cameras I have are only mounted in one direction, so you can only see in one direction. So I had 2 cameras in the front and one in the back and side of the house. This one camera will cover my whole house front and/or back. No waste of expensive electricity either, as it is completely self-sufficient in power thanks to the solar panel that comes with it, which also protects it from harsh weather as a shield or canopy.

The only thing missing from this package is a Micro SD/TIFF card and you're good to go. Very simple and straightforward installation. Just make sure your router is set to 2.4 wireless protocol during installation.

*PS I did not receive an SD card or a SIM card specified in the description.

I am very impressed with the design and functionality of this high quality wireless and solar power camera from K&F Concept. I would give 10 stars if possible. Buy with confidence.

I am very happy with the camera. The supplied solar panel in particular ensures that the battery life (at least in summer ;)) is really great.

This is better made than the other two solar panel brands I own - Big Blue and Solorage.
When charging in high temperatures, cover your device (phone, tablet, power bank, drone battery, whatever) in insulating material like a heavy-duty mailing envelope (cardboard works better than cloth). I've had my devices stop charging at midday with three different solar panel brands - and guess where I live? Florida. At first I suspected the solar panels going bad, and since they're inexpensive enough, I'd buy a different brand. Eventually, though, a notice popped up on my phone - "Charging will continue when the device cools down."
Insulate your device when charging in high temperatures.
Another problem is what I call "backcharge." It's the gradual draining of your device's battery while connected to the solar charger when there's no sunlight. So keep an eye on whether the panels are still in the sunlight or not - which isn't as easy as you might think due to distractions by other things.

I use two of the cameras. One in the garden and one at the front of the house. I chose the camera because I didn't want to drill any holes in the house or put extra sockets. Therefore, the camera with battery operation and solar panel is a good alternative. If you position the camera well for yourself (e.g. near a window on the upper floor), you can easily attach a power bank to it in an emergency.

Furthermore, I wanted a camera that does not necessarily need a cloud, but saves everything on an SD card. If someone wants to steal a camera, they do so. If it's high enough, this isn't impossible, but it's a bit more difficult. Therefore, I personally see storage on an SD card as problem-free.

The camera delivers good pictures and is easy to attach. The setup is also very easy. Install the app on your smartphone, switch on the camera, scan the QR code and off you go to the WLAN. That's it already. For the first start-up I would use the smartphone app, later you can also install the Windows software.

A password is assigned to the camera during setup. You should make sure that your password is secure. So at least 8 characters (better more), consisting of numbers, upper and lower case letters and special characters.

Since the camera has been hanging in the garden for a while, I can already say something about the solar panel. I didn't preload the camera on the back. This was attached immediately when the battery level was 70%. The solar panel charged the battery to 100% in a week. The sun doesn't have to shine directly on the solar panel, it's enough that it's just there. On the front of the house, I don't have direct sunlight. A house is just too far ahead for that. Despite this, the battery is kept at 100% in the morning hours.

What I would like for this camera from K&F CONCEPT in the future:

- The possibility of connecting to a server or to the disk station
- A solar panel with good weak light behavior for retrofitting would make the winter days a little better. I have no experience in winter operation but I can imagine that it will be a little more difficult to charge the battery in winter.

So far, the K&F camera has received a clear buy recommendation from me.

However, the settings also play an important role here. Motion detection and a schedule for when the camera is "on" help save battery. When you are at home, the PIR does not necessarily have to be switched on. If you leave the house for a longer period of time, you can quickly change the schedule with just a few clicks.

Addendum:
It's autumn now and so far I'm still happy with the cameras. I had to recharge the camera on the front once with a power bank (there is a lot of movement at the front door in particular).

Since I placed the camera very well, I got to it very quickly and it was charged to 100% again within half an hour. The weak light behavior of the solar panel is also better than expected.

The support is also very good. The second camera was defective from now on and a new one was sent to me without much back and forth writing. The new one was defective when it arrived and a third one was shipped immediately. Everything uncomplicated and fast. The shipping costs for the return were refunded immediately after a short request.

Two points were decisive for me:
1. The camera should be able to be operated without an external power source.
2. The camera should have online functions.

On point 1:
The 4G camera has a built-in battery. The battery can be charged using the included cable. In addition, a solar panel is included in the scope of delivery, which can be attached directly to the camera or to the wall of the house. In the past few weeks it has been relatively sunny and the battery was always fully charged thanks to the solar panel. I'm curious if that will also be the case in winter.
To point 2:
The camera has a SIM card slot. A sample SIM card is included in the scope of delivery.

The camera can be rotated 355°/ 100° in two directions in the app.
The camera offers a good picture (2K) both during the day and at night.
The two-way sound is acceptable, but depends on where / how high the camera is mounted.

So far I am very satisfied with the product.
